Hello All,
I would like to write a JSL script to select the rows in a table with “complex” conditions:
I need to select ONE ROW per Metric (Column :Metric) with conditions IN ORDER OF PRIORITY:
1- if the condition Flag1 = “FLAG” AND Flag2 = “FLAG” exists, Select Col Max (:Metric1) of this condition
2- if the condition Flag1 = “FLAG” XOR Flag2 = “FLAG” exists, Select Col Max (:Metric1) of this condition
3- Else, Select row Max (Metric1)
Below a tentative code using For Each Row () and a debug column, but my attempt doesn’t work and is not very elegant.
Also, I am not sure how to do an XOR (exclusive OR) in JLS without using combination of basic gates.
Is there a better way to do this?
Note: please find attached a PNG that illustrate my request
Thanks
